Have bought the adapter as part of Black Friday Deals. However, the first adapters had no function in my Audi A3. Whether I try my iPhone 6 to load the original cable or other USB devices - nothing happened. In other cars, no function (to exclude any error in my cigarette lighter). Then came the replacement yesterday. However, here also no function as the first unit. That disappointed me very much. I'll probably let me provide a third one as a substitute for testing. Otherwise, I want my money back - a pity!
